Creating a survey like page

Hello all,

I’m pretty new to Adalo but having a nice progress with some project that I’m building. I’m stuck with something that I can’t figure out though…
I have 3 databases, one for users, one for categories and one for results. I want to ask the users to rate themselves in each category by choosing one option out of 4 (same 4 always) and to store the results in the results database. I also want them to be able to go back to the same page and change their selection. I have 2 problems:

  1. I managed to enable the creation of a new record using a toggle/button but didn’t manage to delete the record when the user is unchecking it.
  2. I didn’t manage to create relationship between the toggles so the user can select only one option at a time.

I also not sure how to store the changes in the page so next time the user will enter the page they will see their progress.

I know it’s a lot but It will be super helpful if someone can figure it out. Thanks!!!
